public WritingOperator()

Method Details

apply

public String apply(org.antlr.v4.runtime.ParserRuleContext node)

The operator that writes the thing node names, or null when this occurrence only reads it. Purely structural (it needs no recorded symbol), so a caller holding an identifier occurrence - of the compiled tree or of a re-parsed body - asks HERE whether it is written rather than re-deriving the grammar's write positions.

Specified by:

apply in interface Function<org.antlr.v4.runtime.ParserRuleContext, String>

Parameters:

node - the identifier node of the occurrence (as RecordedSymbols.Reference.node())
